Not sure
Not sure where the basement water is coming from
If you cannot see where water enters a Oakville basement, do not pick a repair from a menu. Write down whether it follows rain, a crack, the floor edge, or a drain, and photograph the area dry and wet if you can. A sewage smell, or water near the electrical panel or outlets, is an emergency. Anything else can wait for an inspection that names the entry point.
Possible causes
- Note whether it follows rain, a crack, the floor edge, or a floor drain
- Photograph the area, including any white residue or a dark joint
- A sewage smell is a backup, not a foundation seep
Repairs come after the entry point
The four methods — exterior waterproofing, interior drainage, crack injection, and sump pumps — are on the services page. None of them is the right guess until someone can see where the water starts.
When to call
Sewage, or water near the panel or outlets, is an emergency. If the source is unclear and nobody is in danger, wait for an inspection instead of choosing a repair from a list.
This is guidance, not an inspection.
